O Captain! My Captain! Who's the greatest leader in the history of science fiction on television? We're pitting Captain James T. Kirk of Star Trek against your choices, based on the results of our Star Trek Smackdown poll. We're beaming aboard a panel of sci-fi experts to debate the pros and cons of all the leading contenders, but we also want to hear what YOU think, so set your coordinates for the Paley Center and come join the debate.

Bring your tricorders to help you answer some trivia questions to win some Star Trek DVDs! Costumes welcome!

Bonus: Come early to watch a screening of a newly remastered version of "The Cage," the original series pilot, on the big screen! (beginning shortly after 5:00 pm)
